' Application January 24, 1935, -'Serial I In Italy January-26, *1934 Myinvention relates to a combination-of a 1 radio receiver-with anelectromechanical device, in -which-.the. introduction of'a -.counter orof a coin causes fthed-closing -otone or more circuits v which areessentiallor "the operation oi the radio receiver. i I 1 '1 v Aieatureof the invention involves the inclusion .of the mentionedelectromechanical devicein-adetachable casing which may be termed acollector boxadaptedto t'receive the checks;

counters or-coinsdeposited in-the'apparatus, and alsoincludesithe'feature ofhavlngmertain oi the essential p'arts -of theradio indispensable to opable casing: K

According to my invention, the electromechani .caldevicecontained'in-the collector box, aside from certainconnecting-=members allowing the" Each of the two groups of .springcontacts is adapted tointerrupt the circuit, and according 1 to theinvention the first interruption is caused to take placeevery day inorder to induce the owner or tenant to introduce a new counter or coininto the box, where as the second interruption is caused to take placeafter a certain number of days, for exampleafter 30 days, in order toinduce the owner or tenant to detach the box, to pour outthe coincontents, or to bring the box to the oflicewhere the payment is to bemade and where the mechanism is set for a new period of operation.

ence to the annexed drawing showing by way of example a coin-operatedradio receiver with collector box according to the principles of theinvention.

Figure 1 is a perspective view of a radio receiver with the collectorbox detached and Figure 2 is the same perspective view with the samecollector box attached;.

Figures 3 and 4 are an end view and a side view of the inner mechanismofthe box, respectively, and

Figure 5 is a detail of the push button.

InFigures 1 and 2 of the drawing, a radio receiver l is shown, having ona side panel a plurallty of connecting pins 2 adapted to be intro-.eration deliberately located within said detachl radio receiver, as forexample,- the supply circuit.

The invention will now be described with'referduced'into a-correspondingnumber of sockets 3 'of the detachable collector ,box t, which hasexternally a key 5 or a similar winding device, a slot 6 for theintroduction of a coin, a pushbutfun 1 for obtaining by theadvancementof the coin the closing of a-circuitjand thereby the relea'se of theclock work for 24' hours, and'an' observation hole *8 "allowing the usertojob s' 'e ':rve an interior-dial-plate'of a wheel 2 l, t o beffurtherexplained. 1.1

As has already been stated, the inner. mechanism 'of the box 4 comprisesessential parts of the'radio receiver circuit which'is automatically"interrupted at predeterminated intervalsoi time by means of a clockworkand of two groups of spring contacts.

The spring contacts (9' (Fig. 4) have the purpose of causing a dailyinterruption and the spring contacts l8 'causetheinterruption at longerintervals, for example of one or two months. g

The operation of the spring contacts I9 is obtained as follows: when acoin has been introduced in the slot 6, this coin by effect of gravitywill place itself between the small base- II and the arm 20 ofthe lever15. Pushing of'the button I by the user will cause the lever 9 pivotedon the pivot23 to push the coin, which, advancing on the base will'raisethe arm 20 and turn the lever 15 counter-clockwise about its pivot 31.

. The dog 3|. on lever I5 will then engage the catch 32 so that thelever-.15 is not allowed to return to inactive rest position. In thiswaythe tappet 30 of the lever 15 closes an electricc'ontact to be madebetweenthe spring contacts I9 and this contact is maintained until the"lever l5 returns to its rest position. The spring!!! of the clock workis intended to be wound practically each timethat a coin is inserted inorder to cause actuation of the mechanism operated by the introductionof a coin,'etc. vDuring the timezwhen member 31'], which is movedfibythe introduced coin, is effective to close the contact between the groupof contact springs 19, permitting the reception of a radioprogram, thedisk like member i5 is intended to cover winding spindle 34 so as toobstruct access to the winding spindle, thus preventing winding of theclock spring. The operation of the lever l5and the contact springsor'spring contacts may onlybe had when the extension or expansion of thespring 29 of the clock work as indicated at 29 (or an eccentric turnedby the mechanism itself) causes an angular displacement of the lever Hpivoted at 33. g V

Due to the operation of the clock work the apio this at cat i perate ntggct allx-thasa sae paratus is operated so that after the passing of aperiod of twenty-four hours said clock work the toothed wheel 01sprocket 2!.
